PATENT CARL RICHARD 'NYBERCB OF STOCKHOLM, SWEDEN, ASSIGNOR TO WILL I.OHMER, OF DAYTON, OHIO.

HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 596,084, dated December28, 1897.

Application led J'uly 18, 1896. Serial No. 599,749. (No model.)

To all whom. t may concern:

Beit known that I, CARL RICHARD NYBERG, a citizen of Sweden, residing atStockholm, Sweden,have invented certain new and useful Improvements inHydrocarbon-Burners; and

I do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, refio erence being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to improvements in hydrocarbon-burners forsoldering lamps, stoves, duc., and upon which application for LettersPatent is 'now pending in Great Britain.

The object of the invention is to provide 2o means for obviating theinconvenience common to burners as heretofore constructed-v viz., thatthe pipe or pipes surrounding the flame and in which the hydrocarbon isvolatilized can only with great difficulty be cleaned inside-the resultof which is that the burners are generally used as long as possiblewithout being cleaned and are then replaced by new ones. This cleaningconsists in removing the soot or black which is always de- 3o positedinside the pipe when it is highly heated, and hydrocarbon oil passesthrough it at the same time. By arranging a series of curved pipes `inparallel positions independent of each other and disconnected save 3 5with the burner-head they maybe readily detached for cleaning;

In a detailed description of the invention reference is made to theaccompanying drawings.

4o Figure lis a vertical section of an oil-stove having my improvementsthereon. Fig. 2 is an elevation of the burner, showing the pipes mountedin parallel positions. Fig. 3 is a plan view of the burner shown in Fig.1.

A designates an oil tank or reservoir, which is provided with the usualopening B for iilling it, an air-pump C, and safety-valve. From the tankthere projects upwardly a pipe D, fixed to the same and extending almost5o down to its bottom. This pipe is provided at its upper end with aconnecting-nut E, by

lli.

means of which the burner-head I is connected to the pipe D.

The burner consists, preferably, of four pipes, only two of which, F andF', are seen 55 in Fig. l, the other two being just behind F and F' andof the same diameter and curvature.

The pipes F F' and G Cr' constitute two separate and continuous pipeswith uniform cur- 6o vatures in their upper extremities and which areinclosed in the channels M' M2 in a cap The said channels are rounded toconform to the rounded form of the pipes. The oblong broken linesshownin Fig. 3 repre- 65 sent the upper rounded ends of said pipes. Thecap M has a series of projections J', which clamp over the upper flaringedge of a iiameconiner or ring N, and the said cap is thus held rigidlyin position, as shown in the draw- 7o ings. This ring N incloses theupper portion of the pipes and has an inwardly-projecting lower edge,which extends in to the pipes and to which said pipes are soldered. Theheat is directed downwardly along the pipes and is spread over aconsiderable length of said pipes, which prevents a superheating of thegas. It will be Aunderstood the pairs 0f pipes are not connectedtogether, but each consists of a separate and distinct pipe bent to form8o two vertical parallel parts. The independent and disconnectedfeatures of the pipes are important,as thereby the efficiency of theburner may be regulated by the number of pipes that may be placedparallel to each other; and, further, any one or more of said pipes maybe detached for cleaning without removing others. The pipes thusarranged constitute separate canals that enter the burner-head I. Thesaid burner-head is connected to the feed- 9o pipe D by a screw-threadedengagement.. The burner-head is, moreover, provided with two separatechambers I' I2, of which the former,

I', communicates directly with the pipe D on one side, and F and itscompanion pipe F' 95 communicate with the upper ends of said chambers I'I2, and the two adjacent pipes G and G' also communicate with the saidchambers. Chamber I2 also has communicating with it a nozzle I3 of theburner. The cham- Ico ber I2 is provided with an aperture, which isnormally closed by means of a plug I4. The

nozzle I3 is located centrally with relation to the four pipes and thering N. Beneath the burner there is a bowl K, used for lighting.

It is evident that the number of the pipes may vary for burners ofdifferent size and length. Thus, for example, from chamber I' only onepipe or three or more pipes may project,under which arrangement a likenumber of pipes will connect with chamber I2 and the connection betweeneach pair of pipes at the outer ends is the same.

It will be observed that the construction oi the burner-head I, asshown, is essential for the purpose of providing severalindependentchannels between the two chambers.

\Vhen using the burner, the hydrocarbon oil will by the pressure in thetank be forced up through the pipe D and into chamber I', and thencepart of it continues through pipe F and adjacent pipe and the other partthrough pipe F and the pipe adjacent to it in order to enter the chamberI72 and pass thence to the nozzle I3, at which it is ignited. The llamefrom the nozzle passes through the ring N and receives the requisitesupply of air, partly at the lower end of the ring` N and partly throughthe openings N' in the ring. During its passage through the ring thesaid ring,as well as the pipes,is heated suiliciently to volatilize thehydrocarbon contained in said pipes. The standards O are adapted tosupport cooking` utensils or the like.

Ilaving i'ully described my invention, I claim- In a hydrocarbon-burner,the combination with a tank, and a pipe D extending from said tank, of aburner-head I having two separate and non-communicating chambers I' andI2, with the former of which the pipe D communicates, a series of pipeseach one of which consists of a continuous tube having its upper endcurved, and one arranged parallel with the other, and having separateand independent communication with the chambers l" and I2, a cap Mprovided with a series of channels M' and M:2 that inclose the roundedends of the pipes, and a flame-coniining ring` N surrounding the saidpipes, and to which said cap M is attached, the said ring having itslower end projected inwardly and secured to the pipes; and a {lame-jetI3 communicating with the chamber I2, substantially as shown anddescribed.

In testimony whereof I affix my signature in presence of two witnesses.
